You'd think after 30K they'd be bedded in by now! When I find the opportunity, I'll have to go through the bedding in process and see if this indeed is a permanent fix. I kind of doubt it, but I'll keep an open mind.

you maybe too late now, - however you can try a lube spray made by lubegard, its sprayed on the disc surface, the graphite in it fills up some areas on the disc quietining that squeal for good.

lots of mechanic shops use a similar product provided by BG. It definitely eliminates squeal.

The brake burnishing is done on brand new pads. they work awesome after that.
